What should I do if the bulk cement tank falls into the iron block?

1. Use air cannon to break the condensed concrete first, and then shovel it out little by little.

2. Cut a hole in the lower part of the tank and open a lid that was originally screwed with roses. This cover is used for ventilation when work is needed and feeding in an emergency.

3. In the process of canning, people should ventilate the tank, connect the concrete wet and broken by water pipes, break and level the concrete in the tank, and then cut and weld it. Small concrete mixing tank car is a special truck used to transport concrete for construction.
